MoS2 Anti-Friction Engine Treatment 

MoS2 Anti-Friction Engine Treatment 

MoS2 Anti-Friction Engine Treatment ensures immediate friction and wear reduction, adds an extremely protective and pressure-resistant boundary layer with low friction and lubricates during cold starts to prevent damage from lack of oil. Contributes to lower fuel consumption, longer engine life and less noise. Specifically designed for older engine designs with or without a turbocharger.

Pro-Line Engine Flush

Pro-Line Engine Flush

A highly effective formulation designed for quick and safe removal of deposits in engines before an oil change. Optimizes oil consumption, guarantees proper oil pressure in hydraulically activated systems and ensures proper oil flow after a cold start. Allows the fresh oil to immediately develop full performance while restoring full engine performance and reducing exhaust emissions.

Cera Tec Anti-Wear Treatment 

Cera Tec Anti-Wear Treatment 

High-tech anti-wear additive, suitable for most 4-stroke engines as well as manual transmissions and compressors. Reduces friction and wear thanks to a unique combination of ceramic compounds and chemical anti-wear agents. It will prevent direct metal-to-metal contact and reduce friction to increase engine life and efficiency in gasoline and diesel engines.

Cera Tec Anti-Wear Treatment

Hydraulic Lifter Additive

Prevents and reduces hydraulic lifter noise. Cleans oil passages to remove oil flow restrictions. Restores proper hydraulic lifter function and reduces wear.

Pro-Line Engine Flush

Get more from every oil change by starting with our Pro-Line Engine Flush - the cleaner your engine, the better it runs.

Cera Tec Anti-Wear Treatment

Cera Tec is a high-tech ceramic wear protection additive designed for most 4-stroke engines, manual transmissions, and compressors. Its unique blend of micro ceramic particles and chemical agents significantly reduces friction and wear, preventing direct metal-to-metal contact. This leads to smoother operation, enhanced fuel efficiency, and extended engine life.
